What I mean is if you take off normally during the shifts does it feel like a normal 1-2 but when its time for 3rd does it feel like you shifted to neutral? If so you likley have a 3-4 cluthc failure.

If you have a 1-2-neutral shift, it's most likely your 3-4 clutches. Feel free to give me a call if you'd like to discuss it further. 302-250-1202

Thanks,

You could have a stuck solenoid A (1-2) it and soenoid B(2-3) must go off in order to have 3rd.
1st=both on
2nd=A-off B-on
3rd=BOTH OFF
4th=A-on B-off

But generally speaking if the 2-3 shift is being comanded you should set a code. Have you had the car scanned? Or looked at the data stream to see what the PCM is comanding gear wise?

UM..

The CORRECT 4L60E solenoid firing order is:


1st gear: "A" ON "B" ON
2nd gear: "A" OFF "B" ON
3rd gear: "A" OFF "B" OFF
4th gear: "A" ON "B" OFF

Get the car scanned. This could also be a bad 3-2 downshift solenoid, or sticking valve. The "B" solenoid may also be haniging "ON".

If the solenoid is mechanically locked in the "ON" position, it may not throw a code. I use a Snap-On MT2500 for diagostic purposes. It allows me to watch all the commands and see when/if the computer is commanding the shifts. Of course, not everyone has access to one of these scanners, because they are rather expensive.

I stand corrected. I mistakingly switched the 2nd and 4th solenoid layouts. That is a nice scanner I have one also. Much better than the little handheld tuners you see so many of. The only thing I have seen I liked better to veiw data is LS1EDIT.

Actually any more reputable shop would have it or the OTC version,But considering the solenoids are like 20 a peice at the dealer I would just buy both shift solenoids and change them and see what happens. Wouldnt hurt to see whats in the pan anyway .

Shift solenoids are pretty inexpensive and they're easy to change. Just figure on doing a service while you're there. Grab yourself some new fluid, a pan gasket, and a filter. Try to find a Durapreme, or Farpak pan gasket, if you can. They are much better than cork or rubber. Many times, you can only find them at a transmission shop. If you have any questions about changing the solenoids, feel free to give me a call. 302-250-1202.

BTW, I can drop ship you both solenoids, the pan gasket, and the filter for $50 (including shipping).

Thanks,
Frank
